is anyone running a jdm ej20 turbo motor in one of our cars i have searched for it so please dont bash me for not searching. im new to the na to turbo deal but i learn fast. what all will i need for this swap to work. the seller is selling the motor, transmission, intake exhaust manifold, ecu, intercooler, and wiring harness. what else will i need to do this swap with. or where can i find a ej22t motor. there isint many junk yards around here so im limited on options on jy treasures. sorry about the long post. thanks

You will need a turbo crossmember...and 100,000,000 tons of good luck

ok so i would be better off not fooling with the jdm motor. and try to find other ways of making power.

I was just being kinda silly about the needing good luck thing...but if you haven't done an engine swap you might be in for a big surprise as to how much work they are...

So...just figure out what you really think you are capable of...and go from there...

i think i can handle a swap. i am gettin pretty tired of the non turbo deal. the only thing i think will be a problem is the wiring.

95% of a swap is in the wiring. Everything else is just like maintenance, except instead of replacing the old parts with new parts, you're replacing the old parts with different old parts.

Wiring is a bitch-goddess from hell.

Yeah, if wiring is going to be your problem, I wouldn't do the swap, because as Steve said, wiring is all the battle...especially on Subies

i'm also considering doing a swap but want to know if i do mange to find another ej22t like the one i have now. is it possible to get more out of it or should i just swap in an ej20t in place of my old ej22t.
thanks again
oh and sorry for hijacking the thread

Big,
What car are you looking to put this engine into? If it's one of our first gen leggies, it's easy wiring. It's nothing like doing an Impreza swap. You need to add about a dozen wires and switch a handful of pin locations at the ECU. At this point, I can do it without removing the dash. The first time I did it, I did it the hard way. There's a thread on it that's got to be 3-4 years old. What we know has come a long way since then...

ill be swapping in to a 1991 legacy wagon sorry about not specifying. So i guess what im after now is i would be getting the other ecu and harness is there a way i could pull all the wires out of the engine bay and then run the ej20 harness or is that to complicated? thanks for all the info.

Odds are you would be able to do the engine swap and NOT have to do the wiring swap just to get it up and running. If its an older DOHC motor, all the sensors are the same. The only thing I can think that would keep you from running "ok" is the IAC, so swap the NA one back on (or swap the two hot wires). The wagon WILL run, and probably ok as well, but not optimal.....

Matt

will the swap be just as easy in a 94 sedan

If it's a Legacy.

Big,
Why would you want to do that? That requires removing the dash and a lot more cutting and splicing. What you will want to strip from the turbo harness to use the turbo ECU will be the following:

Boost Control
Pressure sensor
MAF
Ignitor

The nice thing is it's all the same area and a little bundle of wires that are pretty easily stripped all the way back to the ECU. You can run the wires through the rubber grommet in the firewall where the clutch master cylinder would mount on a hydraulic car.

You will need to pick up a later Plastic MAF because you car is a '91 (the '94 will already have the correct MAF).

You also need to switch the locations of the cam and crank sensor wire. All 3 wired from each just switch places.

There's a couple other little things that are slipping my mind. I can't remember if it's TPS or IAC poloarity. Maybe someone else wll chime in since I am not firing on all cylinders today.

OR, you could do like Douglas said and just put it in with stock wiring and add a boost controller and maybe an AFC. This is the approach I am currently taking on my '91 even though it's a turbo car. I just don't feel like wiring the ignition conversion right now, so will run the stock ECU with some help...
